Testing laboratories

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The accreditation of a testing laboratory proves that the laboratory produces reliable results with the testing methods that are included in its scope of accreditation. Accredited testing laboratories are industrial laboratories, service laboratories and public research laboratories. Examples of laboratory fields include food, drinking water, environmental water and soil samples, emission measurements, as well as the testing of materials and products.

Testing laboratories use accreditation as a means to demonstrate their competence to their clients. Many tendering processes both in Finland and abroad require that competence is demonstrated through accreditation. Many authorities utilise accreditation when approving organisations for official duties. In such cases, competence requirements have been defined in legislation.

The quality management system of an accredited testing laboratory complies with the principles of ISO 9001. The international organisations ISO, ILAC and IAF have stated this compliance in their joint ​reso​lution (download pdf).


There is close cooperation between authorities in different areas on the development of operations and the exchange of information in the accreditation of testing activities. Examples include the testing of building products in accordance with the EU product legislation (Ministry of the Environment) and testing relating to vehicles, traffic and railroads (Finnish Transport and Communications Agency Traficom).

A technical support group called VERA has been set up for water, food and animal feed analysis, as well as for healthy building analysis. Read more about VERA ​on our website.

Accreditation of testing labor​atories is also implemented in cooperation with international programmes in various fields. The cooperation includes the assessment of doping laboratories with the World Anti-Doping Agency WADA and medical testing with the European Directorate for the Quality of Medicines & Healthcare EDQM, for example.​

Accredited bodies are entitled to use the FINA​S accreditation symbol, which consists of the FINAS logo, the accredited body's identification number and the accreditation requirement.
